IMPROVEMENT IN CARBURETING APPARATUS.

Specification forming part of Letters Patent No. 105,378, dated July l2,1870.

drocarbon to the traverse of the carbonizingair, and in sinking saidtank in the ground below the frost penetration, to insure a uniformtemperature throughout the year; second, in interposing between theair-pump and said tank a long pipe sunk in the ground, to dry and temperthe air before it reaches the tank 5 third, in a drying-chamber filledwith hygroscopic material, and interposed between the air-pump and theoarbureting-tank.

Construction.

stant use.

Partitions a and b extend within an inch or two of the bottom of thetank and divide -it into" cells. These cells communicate with each otherby U-tubes c, making an uptake from Yone cell, and a down-blastilnpinging on the surface of the `gasoline in the next when the machineis working. Air enters the tank by inlet d, and after traversing thesurface of the gasoline in each cell is delivered by outlet e towardtheburners. The tank is sunk in the ground-say, ten feet deep, at anyrate below the action of frost-and is covered with earth. Tube f risesfrom near the bottom of the tank lto the surface of the ground, and isused as a filler to supply the tank with gasoline, or to pump out waste,and tube g is a vent during these operations. to be closed.

Tank T is to be sunk in the ground at, say, forty feet from the house;and the inlet and outlet-pipes are also to be buried, not quite sodeeply at the houseas at the tank--say, with a slope offronov four toten feet, lor one in six or seven. preferable to a volute, because ofthe regularity of its slope.

The temperature of the ground at ten feet deep is pretty uniform in theAmerican cli- At all other times they are mate all. the year round, andby experiment' in the vicinity of Boston is found notto vary much from550 Fahrenheit.

The air-pump of the apparatus is situated in the house to be lighted, asat l?. It forces air through tube Q to tank T, where it arrives at thetemperature of the earth. Being slightly raised in cold weather, it isdrier than it would be ordinarily at that temperature, and will thustake up more hydrocarbon. In summer the moisture will be partlycondensed out of it by lowering the temperature,

'and lthis ilowin g into the tank will sink below the gasoline, and maybe suffered to remain until it is time to clean out the tank. Adrying-chamber iilledwith hygroscopic substance, such as quicklime, maybe arrcnged in this tube, as at N, so as to still further dry the air.The air, charged with hydrocarbon, is returned from tank T by pipe R,and distributed to burners S.

At a given temperature, it is obvious that dry air will carry morehydrocarbon than saturated air; and, as in summer, and indeed, usuallyin winter, the temperature of the house-piping will generally be higherthan that of the tank, the fear of condensation in the house-tubes mustbe very slight.
